Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478620, here are decompositions:

  • 17 + 478603 = 478620
  • 31 + 478589 = 478620
  • 41 + 478579 = 478620
  • 47 + 478573 = 478620
  • 89 + 478531 = 478620
  • 97 + 478523 = 478620
  • 127 + 478493 = 478620
  • 137 + 478483 = 478620

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 478,620 and was likely granted around 1892.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
